Signin
According to the FAA's Aeronautical Information Manual (AIM), a flashing red light signal directed from the control tower to an aircraft means the pilot should give way to other aircraft and continue circling. Light signals are used when radio communication is not possible, and each color and pattern has a specific meaning.
